I am developing an open source sensor beacon board named: YS-Beacon

which contains:

  • nRF52832
  • DAPLink - LPC11U35
  • 9-Axis Motion Sensor
  • Ambient Light Sensor、Proximity Sensor and 3D-Gesture Sensor with Built-in IR LED
  • Digital Pressure Sensor
  • Stereo Microphone
  • 256Mb SPI Flash
  • Battery Charging management

What do you think about it?

  • Nice project. Due to the reason, that the repository on github is closed, is there another way to get the design file?

    Thanks Patrick

  • Thanks puz_md. Your suggest is valuable and I have reworked a new version :)

  • Nice idea, although I don't like the shape very much (sharp edges). Might look 'special' but reduces usability. At least make clean 90° edges on the upper right and lower left corner. I personally prefer plain square/rect shapes or round shapes like the nRF51-Beacon with battery support.

    Also, I think some (two or more) holes for installing the board somewhere would be nice to have (e.g. for robotic projects).

    Are you sure you need the DAPLink interface? I'd rather have a common JLINK interface (did you know, you can use the debugger on Eval boards for beacons like this). So I think the DAPLink will only consume space and increase cost and complexity... and JLINK headers are a must-have for such a project anyway (don't know if they can be implemented additionaly to the DAPLink).

    If you want to use a proxmity sensor, I suggest the CapSense sensors from Cypress, very reliable. Please no capacitive 3D gesture sensors. Simple gestures like Swipe or Push can also be implemented with the CapSense. I think optic gesture sensores would be a bit too much for this design. Light/brightness sensor is ok.

    Battery charging: Might be nice if this supports wireless charging (Qi, connector for coil).

    Maybe USB support would be nice to have, too. Have you considered using the new nRF52840?

    Finally, it would be nice to have a coarse estimation of the production cost. To make this board available to a large maker community, mass production is needed to reduce the cost. Maybe you want to create a kickstarter project if you have a working prototype?

    Anyway, I like the idea and I wish you good luck with your project!
